Abstract

A diode-pumped solid-state laser oscillator having at least one pumping light source (6) that emits light in a predetermined wavelength band, and a laser medium (3) that absorbs light in the wavelength band. In the wavelength band, the optical absorption index of the laser medium (3) increases with an increase in wavelength, and the optical radiation energy of the light source (6) decreases with an increase in wavelength. Thus, with respect to wavelength changes, an increase in the optical absorption index is cancelled out by a decrease in the radiation energy, making the stability of the laser output less dependent on the temperature of the optical pumping medium (6) or laser medium (3).
